Go the distance: New electric vehicle battery charge can last whopping 600 miles

Electric car batteries that can reach a whopping 600 miles before they ever need a recharge — twice the mileage of today’s EVs — are coming to a garage near you, Samsung recently boasted.

Typically, lithium-ion batteries in modern EVs tap out at around 300 miles, with drivers wasting 45 minutes waiting for a charge from 10% to 80%.

The new batteries, however, double the distance and slash the wait time to around nine minutes, the company said.

Solid Energies, one manufacturer of these All Solid-State Batteries (ASSBs), has a good whitepaper explaining the tech (or at least their implementation of it), along with some self-serving marketing material comparing themselves against competing ASSB tech: Superior All Solid State Solutions, Why ASSB.

If this tech delivers on its promises, this will be a game-changer. Not just for electric vehicles, but for all portable rechargeable devices. Higher capacity and less chance of catching fire are both critical to the future of modern electronics.

Looking forward to seeing this in future cell phones and laptops.

IEEE Spectrum: To Make Solid Electrolytes, Start With a Liquid

A solutions-based synthesis can make thin yet strong electrolytes for solid-state batteries

New batteries are often described with comparatives: they’re safer, lighter, or longer-lived than today’s versions. Solid-state batteries—those which contain no liquid—can make two such claims. With inorganic electrolytes, they’re much less likely to catch fire than traditional lithium-ion batteries, which have organic electrolytes. And by swapping out graphite for lithium as the anode, you can get a massive increase (up to 10-fold) in energy density, making solid-state batteries look especially promising for electric vehicles.

While Liu’s project officially ended on 31 January, the team is now in talks with a different federal funding agency and an industry player to continue their work. The goal is to create a working prototype for a solid-state battery with a two ampere hour (Ah) capacity—similar to the capacity of most smartphone batteries today—at a target cost of below US $100 per kilowatt hour (kWh) within the next two to three years.

Cool new tech. Maybe we'll see these in our phones, tablets and laptop computers in a few years.

ECN Magazine: Radical Desalination Approach May Disrupt the Water Industry

Radical Desalination Approach May Disrupt the Water Industry

Hypersaline brines—water that contains high concentrations of dissolved salts and whose saline levels are higher than ocean water—are a growing environmental concern around the world. Very challenging and costly to treat, they result from water produced during oil and gas production, inland desalination concentrate, landfill leachate (a major problem for municipal solid waste landfills), flue gas desulfurization wastewater from fossil-fuel power plants, and effluent from industrial processes.

A Columbia Engineering team led by Ngai Yin Yip, assistant professor of earth and environmental engineering, reports that they have developed a radically different desalination approach—"temperature swing solvent extraction (TSSE)"—for hypersaline brines. The study, published online in Environmental Science & Technology Letters, demonstrates that TSSE can desalinate very high-salinity brines, up to seven times the concentration of seawater. This is a good deal more than reverse osmosis, the gold-standard for seawater desalination, and can hold handle approximately twice seawater salt concentrations.

This is incredible news. Now that we have seen the process in a lab, hopefully it can be scaled up for use in a commercial desalinization plant. A cheap and low-energy technology would pretty much solve the world's fresh water supply problems.
